Yes! But you gave out directly all info needed!!

@FlashInTheNight
on first start there is/will be created a file on (/home/user/)MyDocs named qf (or .qf) which holds some parameters for this (hackable html) app. E.g. if you want to download whole world.maps you need to rise space available (just have a look to that text file).

Well figured out. Do not ask me how much time I spent then as I was looking for info, too (but imagine yourself 3 or more years ago).
